Yonro

He lives next door from Shin-chan's family at room 203. He attended Tokyo Kasukabe University, not Tokyo University as Misae had mistakenly believed. Misae and Hiro frequently invited him over to fancy dinners at their house being very supportive of him so that one day when Yonro goes into a successful political career, he would thank them with lots of money and gifts. When Misae and Hiroshi found out that he wasn't attending Tokyo University, they practically abandoned him. He has visited Shin's family when they moved back into their old house. He works at a supermarket as a part-time job.
